VENTILATOR OPERATION MODES
Ventilation:
the ventilator runs either in air extraction or air supply mode at a set speed.
In this mode some of the ventilators in the network run in air supply mode and the other ones in air extraction mode, depending on
the position of the DIP switch No. 3 (see section
Setting the ventilator operation mode using DIP switches
).
Boost
: the ventilator goes to the maximum speed without changing the operation mode.
Regeneration:
the ventilator runs in two cycles, 70 seconds each, with heat and humidity regeneration.
Cycle I
. Warm stale air is extracted from the room and flows through the ceramic regenerator, which gradually absorbs heat and
humidity. In 70 seconds, as the ceramic regenerator gets warmed, the ventilator is switched to supply mode.
Cycle II
. Fresh intake air from outside flows through the ceramic regenerator, absorbs accumulated moisture and is heated up to the
room temperature. In 70 seconds, as the ceramic regenerator gets cooled down, the ventilator is switched to air extraction mode and
the cycle is renewed. If two ventilators are installed, they operate with opposite rotation directions in this mode. While one ventilator
supplies air, the other one extracts it.
Air supply:
the ventilator operates in supply mode irrespective of the position of the DIP switch No. 3 (see section
Setting the
ventilator operation mode using DIP switches
).
AIR DAMPER OPERATING PRINCIPLE
The indoor unit of the ventilators has a swivel damper. The vertical position of the handle corresponds to the position OPEN, the horizontal
one – to the position CLOSED.
The indoor unit of the
TwinFresh Style Wi-Fi
ventilators is equipped with an automatic air damper. It opens at the beginning of the
ventilator’s operation and lets the air flow freely through the ventilator.
After switching off the ventilator, the damper closes automatically.
The air damper opening and closing process can take up to five minutes.
Caution! If the power supply is cut off during operation of the ventilator, after five minutes, the damper can be manually
moved to the CLOSED position using the handle to prevent drafts.
Later on, when the ventilator is turned on, the damper will automatically open.
Automatic opening/closing of the damper is not provided in the indoor unit of the
TwinFresh Style Wi-Fi M
ventilators. The damper in
these models can only be adjusted manually using the handle regardless of the ventilator operating mode.
Caution! Air damper opening or closing does not turn the ventilator on or off!
The figure below shows the closed and open positions of the damper and the handle.
